Overview

Australian Valve Group (AVG) PTRE15-1400-LF 15mm (1/2") 1400kPa PTR Pressure and Temperature Relief Valve (also known as TPR valve) with an 1" (25mm) extended brass body. The AVG PTRE15-1400-LF PTR valve is designed for hot water tanks with a recessed PTR port thread, where the normal PTR valves cannot reach.  The AVG PTRE15-1400-LF is cross compatible with other popular makes such as Reliance HTE55-1 PTR valve with same fitments and functions.

During the hot water services' heating cycles, the volume of water will expand as the temperature increases. This volume expansion creates excessive pressure inside the water cylinder and must be regulated. The AVG PTR valve is designed to regulate and relieve the pressure in hot water services by dripping in a controlled manner. 2-5L a day of dripping is normal, depending on the hot water usage and the amount of heating going into the water.

The AVG PTR valve is also a mechanical protection device for the hot water services. In rare occasions of faulty thermostat or heating element, the hot water service can overheat and build dangerously high pressures. When the AVG PTR valve senses this abnormally high temperature and pressure, it will dump large amounts of water in hundreds of liters for an emergency pressure relief.

A functioning PTR valve is a requirement by law in Australia for safety and the AVG PTR  valve is approved under the Watermark standard. The AVG PTR valve comes with an insulation jacket and allows for a professional look and minimal heat loss.

A PTR valve usually has a life span about 5 years and needs replacing if you notice excessive water leakage in a stream instead of a controlled dripping. The AVG PTR valve is cross compatible with many other brands such as Reliance, Thompson, Nefa and Reflex.

The AVG PTR valve fits perfectly with mainstream heat pump, solar, electric and gas storage water heater brands such as Rheem, Vulcan, Rinnal, Dux, Aquamax, Thermann, Apricus and Solahart.

Great buy
Our dog is so happy about this. He loves chasing a ball. We also love the fact that it is collapsible and only 12 inches. We travel a lot so it’s perfect for that. I’m enclosing a movie. I did about it for Amazon.

Very disappointed
Unfortunately I ended up being very disappointed with this purchase, after about two weeks of use, it just stopped performing. Not sure what happened but it just stopped releasing the ball and I don't know why, it had no flexibility left to it. I'm not doing a very good job of trying to explain why it quit working but suffice it to say, it became useless after a couple of weeks. Broke my neighbors dog's heart, lol.

This is a big ball.
Larger than I thought but still a great toy for a heavy chew pup, easy to toss and won't go under funiture. She has the same ball in a 5 inch size so I know it's quality and will last. Can't wait for Summer, will make a great yard ball.

Second one, first one lasted a good while
We leave it outside in the weather with solid results for our backyard dog, and the dog loves this thing. It's our go to toy for her, ... perfect for kick to fetch, tug of war, hide in the shirt, bump the human leg when it is wet, etc. ;) The first one we used and used and finally it started to show too much weathering, mildew, and finally breaking after like 1.5 years... we have extremely hot and wet weather here. When new though, these balls take a pounding. Our 50 pound dog can play tug of war to the extent we can pick her up while she holds onto the ball with her teeth. The ball doesn't flinch and the dog loves it. Kicking it is fun because you can give it a wallop and it won't go over the fence since the design absorbs a fair bit of the kick energy, but it is still enough for an adult or teen to send it about 1/4 an acre away. What else... oh the dog has a funny habit of finding the one spot that isn't an empty pentagon... as in the plastic is filled in there... and she likes to bit on that part especially during tug of war. I should also mention our dog literally breaks apart and sometimes eats sticks and twigs in the yard, can't be healthy, so a nice diversion is this ball that she will chew on once in a while without destroying it.

Absolutely love this brand of ball for my dog
I end up replacing these every couple years, yep that's right, years. My border collie will grab this ball in his mouth and then kick another ball around. Don't know why he has to have something in his mouth to play soccer, but he is unique. He managed to tear one of these up when he was in his teething stage, but it took him months, and I took it away as soon as he managed to remove a piece of it. Otherwise, we usually lose these much more often than them getting destroyed through constant chewing, and I suspect heavy weathering outside for an extended period of time. Nowadays he doesn't chew on rubber nearly that often, he has developed his own picky preferences. This ball is his must have for playing around. He loves to drop it down the stairs and play fetch with himself. It's easy for him to grab, it isn't heavy so we don't worry about furnishing, walls, or family members when he is tossing it around. It is much more durable than most, with the exception of really heavy chewers/teething, even then it held up for a long time. As long as you are careful to remove it if they manage to chew through I would even try it out with teething puppies. The lawnmower is also this balls nemesis, it loses every time. If only I could convince the dog that he needs to stop sacrificing toys to the lawnmower :-)
